The invention discloses an internal-circulation type iron-carbon micro-electrolysis reactor. The reactor structurally comprises a cylinder body (1), a water inlet pipe (2), a water distributor (3), an air inlet pipe (4) and an internal circulation pipe (5); waste water flows through the water inlet pipe (2) and the water distributor (3) in sequence and is dispersed into iron-carbon filler (a) which is located on the lower portion of the cylinder body (1), and in the process of being in contact with the iron-carbon filler (a), the waste water is purified unceasingly till post-purification water is formed and drained out of a water outlet (6) of the cylinder body; air enters the iron-carbon filler (a) at the bottom of the cylinder body (1) through the air inlet pipe (4), and aeration bubbles moving upward are formed; the aeration bubbles drive the iron-carbon filler (a) to pass through the internal circulation pipe (5) and be discharged into the post-purification water; the iron-carbon filler (a) keeps on being sedimentated till falling back to an accumulation bed of the iron-carbon filler (a), thereby an aeration cycle of the iron-carbon filler (a) is formed. It is thus clear that by means of the internal-circulation type iron-carbon micro-electrolysis reactor, the energy consumption is low, the abrasion is little, the operation is simple, and the waste water can be disposed in a continuous and highly-efficient mode.

The automatic feeding numerical control lathe comprises a lathe body, wherein a hollow spindle is arranged on the lathe body; a sliding rail is arranged on the lathe body along the front and back horizontal direction; a knife rest is slidably arranged on the sliding rail; a hollow chuck is axially and fixedly connected to the front end of the hollow spindle; a cutting mechanism and an electromagnetic adsorption mechanism are arranged on the knife rest; an automatic feeding device is arranged behind the lathe body; the automatic feeding device comprises a material box base; a material box support is fixedly connected onto the material box base; a material storage box, a corrugated pipe elastic joint and a discharging box are sequentially arranged on the material box support from top to bottom in a fixed manner; a vibration motor is arranged on the outer wall of each of the left and right sides of the corrugated pipe elastic joint; a material baffle mechanism is arranged on the lower part of the discharging box; and a material pushing base which is right blow the discharging box is fixedly connected onto the upper surface of the material box base. The automatic feeding numerical control lathe is simple and convenient for operation, high in automatic degree and stable in work; automatic feeding can be realized; non-cutting time is effectively shortened; cutting can be performed rapidly; and the working efficiency is improved.

The invention discloses a carbon nanotube carrier type microbial electrochemical device for continuously treating sewage and generating power, belonging to the technical field of sewage treatment of microbial fuel cells. The microbial electrochemical device comprises an anode chamber and a cathode chamber, wherein the anode chamber is uniformly filled with carbon nanotubes which serve as anodes and microbial carriers; organic sewage and anaerobic digested sludge are inoculated, the anode chamber and the cathode chamber are sealed by a silicone pad, and an anaerobic environment is formed in the anode chamber; a water outlet of the anode chamber is connected with a three-phase separator. According to the device, the anode chamber is filled with the carbon nanotubes to form a packed bed reactor, the device is easy to operate and free of any catalyst, sewage can be continuously and efficiently treated by a continuous and unconventional batched treatment manner, and when the organic load is 4g COD.L<-1>.d<-1> and the hydraulic retention time is 16 hours, the sewage removal rate can be about 90 percent. Moreover, the three-phase separator is added to the water outlet of the anode chamber, so that the problems of blockage and difficulty in maintenance caused by outflow of carbon particle materials are solved.

The invention relates to an integral multistage microorganism fuel battery pack. The integral multistage microorganism fuel battery pack is formed by serially connecting a plurality of same cubical battery monomers; each battery monomer comprises an anode chamber and a cathode chamber; the anode chamber and the cathode chamber are separated along the diagonal lines of the battery monomers; a proton exchange diaphragm is arranged between the anode chamber and the cathode chamber; a medium inside the anode chamber and the cathode chamber of every two adjacent battery monomers is conveyed continuously, and the proton exchange diaphragm is arranged between the anode chamber and the cathode chamber. According to the integral multistage microorganism fuel battery pack, a conventional microorganism fuel battery structure design is broken, the anode chamber and the cathode chamber of a multistage MFC are nested and fused mutually, the distance between the anode chamber and the cathode chamberis reduced obviously, and the internal resistance of the system is reduced to the maximum extent. Bidirectional interconnecting transfer of protons is formed between adjacent single-stage MFCs, the transmission path cross sections of protons between the anode chamber and the cathode chamber are greatly expanded, and the proton transfer efficiency can be promoted obviously.
